To all whom lit may concern:

Be it known that we,DAv1D LIcHTENsTADT, of Brooklyn, in the county oi'Kings and State of New York, and-RAFAEL PENTLARGE, of the city, county,and State of New York, have invented a new and useful Improvement inBnngs; and we do hereby declare that the following is a full, clear, andexact description thereof, which will enable others skilled inthe art tomake and use the same, `reference being had 'to the accompanyingdrawings forming part of this Yspecilication.

This invention relates to improvements in bungs for barrels, casks, andthe like, and consists in a deep bushscrew, threaded, and with a collaron the exterior for screwing down into and upon the side of the casks,and having a smooth, conical interior ,surface extending from the bottomupward a suitable distance, with an annular recess at the top, abovewhich an annular internal groove isformed by a flange at the top of thebush, into which, through radial notches, a bridgetree, which carries atightening-screw with a plug at the lower end, is inserted, and screwedby turning the ends away from the notches under the ange, so as to Screwthe plug down upon the shoulder, above the conical hole of the bush, allas' hereinafter more fully specified.

Figure 1 is a sectional elevation of our improved bung, and A Figure 2is a plan view of the same.

A is the metal bush, which screws into the hole in the stave, so as tobring the collar B down snugly on the upper surface of the stave.

' This bush has an annular recess, C, at the top of' the conical holeI), and above this is a large annular groove, E, formed by the lateralenlargement of the bush, and the ilange F at the top.

This flange has two radial notches, G, at the top, for the admission ofthe bridge-tree H, which carries' a vertical tightening-screw, I, with aplug, K, swiveled to the bottom and fitted to screw downvnpon theshoulder' of the recess C.

This plug is provided with a packing-ring, lL, of any suitable exiblesubstance, and may have an exten` sion, M, ofcork or other substance, ifpreferred.

The ends of the bridge-tree are tted to'turn freelyv in the groove E, sothat it may be readily put in and taken ont, and the plug is so arrangedas not to bind in the hole of the bush if the'pressure ofthe screw I istaken ofi', whereby the application and removal of the plug is made verysimple and easy.

This bung may be used also as a vent-plug, by raising the screw Isuioiently to admit the air.

Having thus described our invention,
